Fig. 4l; is a detail view showing in top plan the sleeve section ot' the `yoke comprised in the tool shown in the precedingr views.

`Referringspeciteally to the drawings in which similar reference characters roter to `similar parts, my invention, in its present embodiment. comprises a yoke designated `generally at Y which 1s of suhstantlally U- torm and which consists of a right angular intermediate section 1 5 connected` at one end to a curved track section 16, and at its oppo- `tit-intimi lll is connected and includes a sleeve site end to a terminal linger section i7. To

the tree end of the track section 16, a sleev serial im. 522,331.

shown in l?. ,D its clearly shown in lling. l, the confronting ends oit all the `sections ol the yoke are` tubular to thiiieadedly ieeei ve the opposite enfle otshanks 22 which are oppositely threaded to allow .ol an adjustment of one section with respect "to the other. The shankconnecting` .theseetons` 15, and lofisprovided with nuts @4i-lay Ineens ot which the` sections can loe locked in lany adjusted position upon the shank. j

From the 'to1.e2;oiupr constructionit 'will he elear ythat the yoke Y justed to vary y th e dist ance between `the vsleeve 19and the lingers `21, on widened to vary the horizontal i position l ot the. sleeve and fingers With relation tothe sections 15, and e showinlinlig. lythe spindleQO, isserewthe position aeollar 255 loosely ltterl (on, the

This ar is provided with a spindle.

of metal lient in the `torni ot a ll. lllpepan allel portionlso'l the lever are adapted tol ten v` upon .opposite si of the track section 16 ot the yoke as is clearly shown in Fig. 2, and a roller 3l isrotatably sustained upon a pin 32 mounted in the lever to have rolling Contact with the inner edge of the track 1G.

As shown in Fie'. 1, a coiled expansilole and relatively light spring 33 is mounted on the spindle hetvveen the crankl 25 and the Sleeve i9, this springr serving-to normally ele `vate the spindle and to thus facilitate the application of; the tool to a valve.

In the applied position of the tool with relation to the valve V and a valve spring `S as shown` yin Fig. l, the fingers 21 are ladaptedto surround the stem V of the valve and to engage a Washer Bil. The lower end i 'of the spindle 20 engages the head of the tvalife directly above the stem V". With areeurved 4on the sainearc. H0 y as aunity can heradl y tional yoke ot rto the dotted line position effects :in elevation ou the entire yoke Y with relation to the spindle 20, the pivot point Si() acting es n 'tulcrnin tor the lever, :1nd the curved truck 16 and roller-3l cooperating` to eiect such elevation of the yoke. lilith the yoke in elevated, position, it will be clear that the iingers 2l are likewise elevated to effect a coinpression of the spring S and to thus :illow removal of the spring retaining` pin 35. lt is to be particularly noted that when the lever reaches the inclined position Shown in (lush linesin Fig. l. the downward pull exerted by the spring` S will be ineffective to swing 'the lever dmii'iweriglly pest deed center ,so that the lever and. consequently the yoke nniintfiined in eleyntotl position witl'iont the neceeeity of holding` the lever in Suchpoeition. This obviously allows of the operator completely releasing` the tool lso tlnit lie een employ both bends in etectingrn removal ol the spring or valve. v

'By virtue oil? the control and :id'insizibility of" the yoke Y. it will be .nniniftedA tontlhe tool een be readily applied to various lornis of .engines andtliztt theH yoke will extend nronnd any extrfineons` apparatus situated on or adjacent to the' engine, thus permitting` `ost, the proper positioningi oi the 'spindle :Z

and the' lingers 2l in effecting the lifting and compression'of the valvespring. Through the adjnstability of the nut 26 the throw Vot theleyer lcan likewise be Varied to permit ot the application oil the tool to Springs ol Cliilerent tensione and lengths. Y

Although halve herein shown sind described only one 'form oit' tool embodying my invention7 it is to be nnderetood that Varion'schanges and niodiiiezitions may loe made herein without del'oartiin;v 'roiny the spirit ol the invention and the spirit :find scope 'ot the appended claims.
